1. A transmission for translating pedaling into movement of a bicycle, comprising:
a multi-speed freewheel including a first driven wheel and a second driven wheel;
a first drive wheel continuously connected to the first driven wheel having a first gear ratio;
a second drive wheel continuously connected to the second driven wheel having a second gear ratio, the second gear ratio different than the first gear ratio;
the multi-speed freewheel configured such that rotation of the first drive wheel and the second drive wheel in a non-drive direction causes a driving engagement toggle between the first driven wheel and the second driven wheel.
